' SAFETY DEVICE EOEAMUSEMENT RIDEs Filed Feb. 4, 1949 -s sheets-sheet s Patented Apr. 15, 1952 UNITED stares are t orrice This invention relates generally to amusement devices andv particularly to a safety device for amusement rides.
The main object of this invention is to produce a safety device to lock the passengers in their seats with the maximum degree of safety and at the same time reduce the time required for loading and unloading passengers, thereby greatly increasing the number of rides which may be given in a given period of time.
The second object is to so construct the device that. its `operation is entirely automatic and selfadjustable to the sizes of the passengers.
The third object is to so construct the device that there is no way in which it can be rendered inoperativev by careless or intentional action on the part of the passengeror attendant, as long as the door of the cage is closed.
I accomplish these and other objects in the manner set forth inthe following specification as illustrated in the accompanying drawings, in which.:
Fig. 1. is a fragmentary perspective view in which a passenger is shown on a seat and being held by. the safety strap and showing the cage removed.
Fig. 2 is asection taken along the line 2-2 in Fig. 3.
Fig. 3 is a fragmentary side elevation of Fig. 2.
6 Claims. (Cl. 1554-189) Fig. 4 is an enlarged fragmentary section taken l" along the line 4 4 in Fig. 3 showing the safety pin on the lock.
Fig. 5 is a perspective view'of actuating bar.
Fig. 6 is a perspective view similar to Fig. l but showing the door open and the strap in a released position.
Fig. 7 is an end elevation of a car from the supporting end.
Fig. 8 is a view similar to Fig. 2 but showing the door open and the strap released.
Fig. 9- is a fragmentary perspective view of the door hinge and its connection to the operating bar.
Fig. 10 is a fragmentary view of the hinge for the strap arm.
Fig. 11 is a perspective view showing a cornplete ride.
Like numbers of reference refer to the same or similar parts throughout the several views.
Referring in detail to the drawings, there is shown a base l5 upon which is erected a rigid mast I3 upon which is mounted a wheel whose spokes I1 are revolvable in a vertical plane by means of the cables I8 which pass around the shoes I9 on the outer ends of the spokes I1.
Power is supplied to the cable I8 from the motor 23 under the control of an attendant.
At the outer ends of the spokes I1 are mounted the cages 2l which are somewhat oval but which may assume any desired shape. The lower portion 22 is usually made of sheet metal orfabric and the upper portion 23 of wire cloth or transparent plastic.
Each cage 2l is revolvably mounted on a horizontal stub shaft 24 which journals in the bearing 25 on the outer end of the spokes I1. The frame work of each cage 2l includes a floor 26 which is supported transversely by the tubular beam 21 at whose ends are mounted the upright posts 28 and 29 which are joined by the back bar 33. Side frames 3| and 32 extend forwardly from the posts 2e and 29 and serve to support the cage 2l.- A post 33 extends upwardly from the frame 32 parallel with the post 29 and joined thereto by the curved hand rail 34.
The posts 33 and 29 are also joined by a horizontal plate 35 to which the stub shaft 24 is secured. To the post 28 is attached the door frame side 35 by means of the hinges 31. f The rail 39 of the door 39 is straight and its front side lil is joined by a curved portion 4l to the lower side 32 which is integral with the side 36. Between the top rail 38 and lower side-42 are secured a pair of parallel rails 43 havingv latching bars M secured between them.
f The door frame side 36 has also formed thereon a lever 45 which is fixed with relation to the door 39.
AThe upright posts 29 and 33 have projecting therefrom the lugs 46 which support the hori- 'zontal rock shaft 41 to which is hinged a bowed strap arm 48, between whose ends is secured the flexible strap 49 of canvas or other suitable material. On the swinging end of the arm 48 is mounted a protruding latch point 53 capable of passing through any of the openings 5l in the ladder-like structure formed by the parts 43 and 44. The point 59 is provided with a hole 52 for a safety pin 53 which may be in any desired form to prevent unauthorized opening of the door 39.
The shaft l1 has projecting therefrom a lever 54, to which are attached the straps of a sleeve 56, through which slidably extends the rod 51 which extends from the end of the tubular connecting rod 53 which is connected to the lever 35 by the pin 59. A cotter key 50 passes through the rod 51 between the straps 55.
On the rod 51 is placed a compression spring 6l between the sleeve 56 and the rod 58.
Rides of this type are commonly equipped with brakes which make it possible for the rider to rock and even completely overturn the cage. (See my co-pending application, Serial No. 23,171, led April 26, 1948, and now abandoned.) A seat 62 and seat back 63 are mounted Within the structure being supported by the back bar 30 and on f the seat supporting legs 64 which are supported by the side frames 3| and 32.
The operation of the device is as follows: Upon the closing of the door 39, the strap arm 48 and its strap 49 are forced down under the compression of the spring 6l causing the strap 49 to rest firmly across the lap of the rider. When the door 39 approaches its closed position, the latch point 50 will enter the opening 5l with which it happens to register so that the final closing of the door causes the arm 48 to be held down positively until the door 39 is again opened.
It can be seen that by this construction the strap 49 is automatically adjusted to the size of the person and the rmness of the application is increased with the size of the person.
In most cases a keeper of some sort, such as the pin 53 or its equivalent, should be employed to prevent any careless or intentional release of the strap 49 during the ride.
It can be seen that this device not only makes the ride completely safe but it also greatly increases the earning capacity of the ride.
Since the total riding time seldom exceeds one minute. it can be seen that the loss of a few seconds in loading and unloading each cage can easily total the riding time and due to the automatic action, my ride is able to show as much as a 50 per cent increase in revenue on certain types of ride.
